of the class III antiarrhythmic agent 1-[2-hydroxy-2-[4-[(methylsulfonyl)amino]phenyl]ethyl]-3-methyl-1H- imidazolium chloride, 1 (CK-1649), were prepared and investigated for their class III electrophysiological activity on isolated canine cardiac Purkinje fibers and ventricular muscle tissue. Structure-activity relationships are discussed for a series of 11 compounds. One compound, N-[4-[1-hydroxy-2-(4
制备了III类抗心律不齐药物1- [2-羟基-2- [4-[(甲基磺酰基)氨基]苯基]乙基] -3-甲基-1H-氯化咪唑鎓的新类似物1(CK-1649),研究了其对离体犬心脏Purkinje纤维和心室肌组织的III类电生理活性。讨论了一系列11种化合物的结构活性关系。一种化合物N- [4- [1-羟基-2-(4,5-二氢-2-甲基-1H-咪唑-1-基)乙基]苯基]甲磺酰胺盐酸盐9的活性与1 in十二指肠内给药时,体外和延长了麻醉犬的功能不应期。与1不同,化合物9在急性心肌梗死后24小时内不能有效地防止麻醉狗的程序性电刺激引起的室性心动过速。
